Calgary played its first season in the Patrick Division before moving to the Smythe when the NHL realigned along geographic lines in 1981.[3] The Flames qualified for the playoffs each year from their arrival in 1980 until 1991.[4] During that time, they won two Presidents' Trophies as the NHL's top regular season club, 1987–88 and 1988–89,[5] captured the Clarence S. Campbell Bowl as Campbell Conference champions twice, 1985–86 and 1988–89, and won the Stanley Cup in 1989.[1] The Flames fared poorly following their Cup win, failing to win another playoff series until 2004, a span of 15 seasons, during which they missed the playoffs eight times.[4] The team returned to the post-season in 2004, making an unlikely trip to the finals, during which the team captured its third Clarence Campbell Bowl by winning the Western Conference championship by becoming the first team in NHL history to defeat three division winners.[6] Overall, the Flames have made 20 appearances in the Stanley Cup playoffs in their 28 complete seasons in Calgary, including the last five consecutive seasons.[4]
